To me its looking like it is not a case of all solar installations are
evil. My guess is that most are not. I know at least 5 hams with arrays
directly under their antennas and they have no noise issues. Case in point
for me is the array 2 houses the other direction. I never heard a thing out
of it.
The disturbing bit to me is that I was told by Solar City that this is ONLY
type of system they install and I am guessing they install a lot of them.
Please see ns6q.net/exams for all the details about out exams...
